Housing experts are warning that they could get a boost from the Federal Reserve due to the rapid rise in rents.

Mortgage costs are going up as the central bank raises interest rates to cool down the economy and contain inflation. If people who wouldn't have bought a home stayed in apartments and rented houses, it would compound demand and keep rental prices high.

It's hard to say how long the rental demand boost will last, but it could make it harder for the central bank to bring inflation down. Rent-related costs make up nearly a third of the Consumer Price Index inflation measure and anything that helps to keep them climbing at a brisk pace is likely to perpetuate rapid inflation.

According to Apartment List, rents on new leases went up in the year through June. The pace of growth is still an unusual one, even though it is slightly less than in the previous year. The annual increase was usually 2 to 3 percent before the Pandemic. The recent market rent increases have trickled over to the official inflation data.

As people go to re-sign their lease, they see that it is hundreds more dollars than last month, and thousands more dollars than last month, according to an economist at the housing website. Rent prices are going to continue to be pressured.

Gail Linsenbard lectures on philosophy at a college in Boulder, Colo., but housing in the area has gotten so expensive that she has been teaching from a friend's place in New York.

Dr. Linsenbard said that she couldn't afford to live in Boulder because of the high rents. The situation has disrupted her life because she can't rely on a national network of friends.

She preferred her own place.

The rising rents have become a thorn in the side of the Fed. The recent surge in rents is related to longer- running fundamentals and not coronaviruses. The need for apartments and leased homes has grown as members of the massivemillennial generation grow older and move away from their parents and roommates.

The demographic trend was accelerated by the Pandemic. After being exposed to diseases, people looked for their own places.

According to a report from the Joint Center for Housing Studies at Harvard, builders were completing units at a rate of 349,000 per year in the early part of the next decade. The number of occupied apartments more than doubled.

America's rental vacancy rate slumped as apartment supply struggled to keep pace with soaring demand, and was stuck at levels not seen in the 1980s through the start of 2022,

The run-up in market rents has trickled into official inflation data as people renew their leases. Rent of primary residence increased by 5.2 percent in the year through May, and new data will be released this week.

I'm worried about the outlook. With persistently high inflation, rising consumer prices and declining spending, the American economy is showing signs of slowing down. There are other measures that signal trouble.

The consumer is confident. In June, the University of Michigan's survey of consumer sentiment hit its lowest level in its 70 year history, with nearly half of respondents saying inflation is hurting their standard of living.

There is a housing market. Construction of new homes is slowing due to decreased demand. As interest rates rise and real estate companies lay off employees, these trends could continue.

There is a substance called copper. A commodity seen by analysts as a measure of sentiment about the global economy because of its widespread use in buildings, cars and other products is down more than 20 percent since January.

There is oil Because of supply constraints caused by Russia's invasion of Ukraine, crude prices are up this year, but they have recently started to fall as investors worry about growth.

The bond market is a place to buy and sell bonds. Long-term interest rates in government bonds have fallen below short-term rates. It shows that bond investors think the economy is going to slow down.

More supply should be on its way because a large number of new apartments and condominiums have been started since the outbreak of the swine flu. Real-time rent trackers have slowed in some markets.

New buildings are taking a long time to finish due to shortages of labor and supplies needed to turn blueprints into reality, and it is uncertain when those challenges will be solved. At a time when the nation is short about 1.5 million housing units that are affordable and available to lower-income renters, new apartment and housing developments skew towards high-end and luxury units.

It is not known how well the supply will match the demand.

It is unlikely that rental prices will fall from the highs they have reached in the past year because people are still competing for apartments. Labor and utility costs for landlords could go up faster than usual.

Rent growth will probably be moderate to some degree, according to the head of economics at RealPage. He said that costs are going up for landlords and demand is still strong.

The Fed's rate increases will make things worse.

More people will have to renew their lease as rates rise because they may have thought they had enough money for a down payment. Rental demand is going to rise.

Housing experts said that the potential boost will fade. Rents are likely to go up if the economy slows sharply, as people move back in with roommates or family members, and rental demand goes down.

A slowing of wage growth is the main thing that would cool down the rental market. A lot of the lifestyle gains that came with more and better housing are likely to reverse.

The transition could take a while. Wage growth has remained strong despite the fact that inflation has not been accounted for.

In the meantime, an already limited supply of rental housing could be reduced as the Fed's rate moves push up financing costs and deter developers. The central bank raised interest rates from zero to 3.5 percent by the end of the year.

New home construction fell to the lowest rate in more than a year in May as borrowing costs climbed. Industry executives can attest to the impact that apartment construction is having.

The question of whether to build has been clouded by inflation, rising interest rates, and the disruption of supply chains, which has builders worried.

The risks have led to the lender turning more conservative by requiring developers to put more of their own money into projects.

Mr. Wali said that as the lack of new development works its way through the system, supply will be even more strained. The upside is that rising rental demand makes him feel good about the rents on the apartments he already owns.

He said those are great.

It is possible that the nation is seeing a shift in rental markets. Rent growth was seen in places like Rochester, N.Y., and Orlando, Fla., as a result of remote work. Even as offices recall workers and coastal markets like New York City heat up, some cities in the middle of the nation are cooling.

Samuel Himmelstein, a tenants' rights lawyer in New York City who has been practicing for 42 years, said that he has never seen the demand for rent increases like they are today.

The rental crunch could be helped by national housing policy. Housing groups argue that more congressional action is needed to fully address the shortage of affordable units across owned and rented housing, even though the Biden administration has proposed a series of measures meant to foster more affordable housing construction.

Eric Parks has observed that the market for purchased homes is slowing even as the rental market is hot. A duplex in South Lake Tahoe, Calif., was listed by an online college professor in May for $899,000, but no one was interested. He received only low offers despite cutting the price.

He decided to rent the Reno, Nevada, condominium he had been living in for over a year to a traveling nurse, who was one of 18 applicants, while he moved back to the duplex and listed it for $2,500. It was a success.

He didn't think the listing would result in no offers. The market for rentals is crazy.
